I have already personally confirmed that Denuvo can make Sonic Superstars unplayable, causing an error message 'For the first launch go in Online Mode' even if the game had been launched before. Principally it phones home periodically, and if it cannot do so (either the user is offline or the servers are down, which has happened several times in recent years), the game will not run at all. ContextDespite the lies of its creators and now its owners Irdeto, Denuvo Anti-Tamper does 'have any negative impact on a game or customer experience'.
